Junior Guerra

Career
Early years
In October 2001, the Atlanta Braves signed the then 16 year old Guerra, as an international free agent out of Venezuela, to play as a catcher. After being converted to a pitcher in 2006, he was released by the Braves and signed with the New York Mets in 2008, where he gained traction but failed a PED test in 2009.
In 2010, he signed with Sant Boi of the Spanish División de Honor de Béisbol in Sant Boi de Llobregat. Guerra spent some time at first base en route to winning a championship in the league. The following season, Guerra returned to the United States where he played for the independent Wichita Wingnuts. He spent 2012 with the Leones de Yucatán of the Mexican League before returning to Wichita in 2013. In 2014, he pitched for San Marino of the Italian Baseball League, winning eight games and putting up an earned run average of 1.29 en route to winning the European Cup.

On May 30, 2018, Guerra pitched six shutout innings against the St. Louis Cardinals and allowed no walks. Guerra avoided the major injury problems that plagued him in prior seasons, appearing in a then-career best 31 games, but finished the 2018 campaign with a 6–9 record and a 4.09 ERA.
